Update heat-agents setup files

This patch moves the image pull step out of the service heat-agent
service script to ease the service init process and to make it more
reliable. By doing this outside of the service script, it's possible to
know when the `firstboot` script failed and report back.

It also updates the firstboot yaml file to point to the
`tripleoupstream` org.
